Second,input the command line in cmd.exe dialog box.The most important step in the conversion of wmf to j2k is inputting command line.The main structure of command line should be like this:
“htmltools.exe” “input.wmf” output.j2k
Here are the example to explain the command line above.
"C:\Documents and Settings\admin\Local Settings\Temp\htmltools\htmltools.exe" "C:\Documents and Settings\admin\Desktop\New Folder (2)\AN00914_.WMF" 01.j2k
"C:\Documents and Settings\admin\Local Settings\Temp\htmltools\htmltools.exe" is the path of called program—htmltools.exe which is the executable file in HTML Converter Command Line.The path is too long to input,so you can drag the file into cmd.exe directly for convenience.
"C:\Documents and Settings\admin\Desktop\New Folder (2)\AN00914_.WMF" is the path of source file which you can drag into the dialog,too.
01.j2k is the name of target file.
Third,just find the target file in current directory.If you specify the path for target file,the file will be saved in specified directory.
